Fix

  • Log in to Netlify
  • Choose your app and click on Site settings
  • Navigate to Build & Deploy
  • Under Continuous Deployment select Edit settings
  • Scroll down to Environment variables and add a new Variable with the following values

CI = false

Thanks. This solved the problem for me.
I used yarn and already had a yarn.lock file so automatically the Build command already had 'yarn build' so all i did was add CI = to the yarn build and it worked.
Like
Build command: CI= yarn build.

But for npm it would be
Build command: CI= npm run build

Hi, I'm almost completely new. I tried CI= npm run build but it didn't work, I guess I'm doing sth wrong. Any ideas on how to fix this on vercel?

On vercel and netlify, setting CI to false in environment variables make it work XD

THANKS !!

CI=false npm run build
working in gitlab ci
but in other cases, i think
Ci='' would be good
because sometimes the false string means true not false

Hi @kapi1 Im wondering what's the drawback when we disable the CI option? Is this flag only treats warning as error or it serve another purpose?
